[PATCH 055/103] qemu: command: Introduce JSON variant of qemuBuildRomProps
Add a JSON variant of the generator 'rom' properties. For convenience
both the old and new are for now marked as unused, which will be removed
once the conversion is complete.
The formatted properties have following types according to QEMU.
'virtio-blk-pci' was used as an example:
rombar=<uint32> - (default: 1)
romfile=<str>
